summary This paper presents a teaching experience involving students and professors from various universities, in Italy and abroad, which began in 1996 and is still on going. The Virtual Studios on the Internet (VSI) have some features in common with the Teaching Studios planned for the new programme of the faculties of Architecture in Italian universities. These are the definition of a common design theme, and the participation of disciplinary teachers. The greatest difference is in the modes of collaboration, which is achieved through information and communication technologies. The chief result of this is that the various work groups in different places can work and collaborate at the same time: the computer networks provide the means to express, communicate and share the design project.

summary The building industry involves a larger number of disciplines, operators and professionals than other industrial processes. Its peculiarity is that the products (building objects) have a number of parts (building elements) that does not differ much from the number of classes into which building objects can be conceptually subdivided. Another important characteristic is that the building industry produces unique products (de Vries and van Zutphen, 1992). This is not an isolated situation but indeed one that is spreading also in other industrial fields. For example, production niches have proved successful in the automotive and computer industries (Carrara, Fioravanti, & Novembri, 1989). Building design is a complex multi-disciplinary process, which demands a high degree of co-ordination and co-operation among separate teams, each having its own specific knowledge and its own set of specific design tools. Establishing an environment for design tool integration is a prerequisite for network-based distributed work. It was attempted to solve the problem of efficient, user-friendly, and fast information exchange among operators by treating it simply as an exchange of data. But the failure of IGES, CGM, PHIGS confirms that data have different meanings and importance in different contexts. The STandard for Exchange of Product data, ISO 10303 Part 106 BCCM, relating to AEC field (Wix, 1997), seems to be too complex to be applied to professional studios. Moreover its structure is too deep and the conceptual classifications based on it do not allow multi-inheritance (Ekholm, 1996). From now on we shall adopt the BCCM semantic that defines the actor as "a functional participant in building construction"; and we shall define designer as "every member of the class formed by designers" (architects, engineers, town-planners, construction managers, etc.).

title SHARED SPACE’ AND ‘PUBLIC SPACE’ DIALECTICS IN COLLABORATIVE ARCHITECTURAL DESIGN.
source Proceedings of Collaborative Decision-Support Systems Focus Symposium, 30th July, 2002; under the auspices of InterSymp-2002, 14° International Conference on Systems Research, Informatics and Cybernetics, 2002, Baden-Baden, pg. 27-44.
summary The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article.

Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components.

Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

title A STEP Towards a Computer based Integrated Building Design System
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary Building design is a multi-actor and multi-task process. In a design project architects, engineers and other specialists need to exchange information in order to produce a coherent design. These design participants often have different views of the design from their own perspectives. The aim of an integrated building design system is to develop a building data model that integrates all views so that building information can be exchanged in electronic form between the designers and also throughout various design stages. This paper introduces an integrated building design system developed as part of the European project, Computer Models for the Building Industry in Europe. It concentrates on the development of the Data Exchange System which is a central data repository implemented using an object oriented database and ISO STEP technology and it is able to support concurrent engineering, versioning, history tracing and other data transaction management

summary From the first artistic expressions of mankind, the Mathematics has influence the shapes and proportions presents in the different artistic disciplines. The coming of Abstract art and modern Mathematics at the beginning of the century supposed a complete renovation of the way of understand the relationship between Mathematics and Art, reinforced by the huge expansion of computers nowadays. Chaos Theory or Fractal Geometry constitute examples of this tendencies, that normally are expressed in the two dimensional plane. The idea of this work consists on the utilisation of a series of elements from the contemporaneous Mathematics to express them in an artistic way in the three dimensional space. The result is a family of objects that we have called CYBERSCULPTURES, due to their sculptural character and the fact that they have Internet as their virtual museum.

title A digital Procedure of Building Construction: A practical project

summary In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title Conjoint measurement in virtual environment: a framework
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary Conjoint analysis (also called stated preference analysis) involves the use of designed hypothetical choice situations to measure individuals' preferences and predict their choice in new situations. Conjoint experiments involve the design and analysis of hypothetical decision tasks. Alternatives are described by their main features, called attributes. Multiple hypothetical alternatives (product profiles) are generated and presented to respondents, who are requested to express their degree of preference for these profiles. Conjoint experiments have become a popular tool to model individual preferences and decision-making in a variety of research areas. Most studies of conjoint analysis have involved a verbal description of product profiles, although some studies have used a pictorial presentation of product profiles. This paper describes a framework for a conjoint analysis system in a virtual environment. Product profiles are generated in a virtual environment and respondents are requested to choose in that virtual environment the product profile they prefer. Advantages of a virtual environment in this area of research include 3D presentation, improved experience and the possibility to include measurable attributes such as time and sound. This framework is a first attempt to explore the possibilities of virtual reality systems in conjoint analysis.

title Road hierarchy and speed limits in Brasília/Brazil
source H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

title On Linguistic Aspects from a Cross-cultural Perspective
source International Conference on Generative Art
summary The goal of this paper is to discuss the issue of culture and its relationship to language and cognition by dealing with a number of lexical concepts, grammatical concepts and cultural scripts. Taking a moderate view, I reconcile universalism and ethnocentrism and argue that the study of culture-specific aspects of language has both a theoretical and practical importance. The role of universal semantic primes is obvious in culture-specific words such as the Japanese amae (a peculiarly Japanese emotion) which, though unique and untranslatable, can be accurately and intelligibly defined in terms of semantic primes (Wierzbicka, 1996). The view that meanings cannot be fully transferred from one language to another is supported by the difference in meaning manifested in the different range of use of the word happy (a common, everyday word in modern English) and joyful (a more literally and stylistically marked term.). A cross-linguistic analysis of the concept ‘happy’in English, Romanian, German, French, Italian, points to the so-called ‘traditional Anglo-Saxon distate for extreme emotions’. As far as aspects of grammar connected with culture are concerned, I compare expressive grammatical devices like intensifiers in English, Romanian and Italian. The question the paper addresses is whether constructions like syntactic reduplication(e.g. bella bella) and the absolute superlative (e.g. bellissimo) are indeed linked with what has been called ‘the theatrical quality’ of Italian life (Barzini, 1964) or not. Relative to Romanian, I assume that the idea of intensity of a state or action is conveyed, in certain registers, by terms and expressions pertaining to basic element source domains such as fire (e.g. frumoasa foc ‘fire-beautiful’) and earth (e.g. frumusetea pamantului ‘beauty of the earth’) and also by syntactic reduplication (e.g. frumoasa-frumoaselor ’beauty of the beauties’). Finally, I approach aspects of pragmatics which are culturally determined in the sense that they express cultural norms, values, ideals, attitudes. For instance, preferences are expressed directly in English while in Japanese this manner is contrary to the ideal of enryo ’restraint, reserve’.

title Pianos Not Stereos: Creating Computational Construction Kits
source Interactions, 3 (6)
summary The stereo has many attractions: it is easier to play and it provides immediate access to a wide range of music. But "ease of use" should not be the only criterion. Playing the piano can be a much richer experience. By learning to play the piano, you can become a creator (not just a consumer) of music, expressing yourself musically in ever-more complex ways. As a result, you can develop a much deeper relationship with (and deeper understanding of) music. So too with computers. In the field of educational technology, there has been too much emphasis on the equivalent of stereos and CDs, and not enough emphasis on computational pianos. In our research group at the MIT Media Lab, we are developing a new generation of "computational construction kits" that, like pianos, enable people to express themselves in ever-more complex ways, deepening their relationships with new domains of knowledge.

summary While looking at glasses, we will have various sensation on their forms, colours, textures etc. These feelings direct us to decide which pair of glasses to buy. This study tries to find out the relationship between human sensation and glasses design; that is, to figure out what kinds of forms will excite what kind of human sensation. By adopting this relationship, we also propose a computer support system which can automatically generate appropriate glasses forms in response to the expectation of consumers. In this study, we first collect several adjectives which can express the human sensation on glasses designs. Then, in an experiment, subjects are asked to evaluate a set of glasses in order to acquire the ratings of those adjectives. We further analyze the formal elements included in different glasses, multivariate analysis and the neural networks are used to decide which design of each element are more likely to excite a specific human sensation. These results then are built as a knowledge base of a support system which includes an inference engine to assist a designer to produce new glasses design. By receiving the input of desired adjectives, this system will find out the most preferred elements for each adjective and integrate them into some appropriate design prototypes for further modification.

doi https://doi.org/10.52842/conf.acadia.1996.183
summary Architects and designers use multiple media to explore and express design solutions. The physical model remains one of the most important media to represent the architect’s work that cannot completely be substituted by computer graphics.

The experimental use of various media is of major Importance for architects. Nevertheless, the author of this article is convinced that architects and designers will continue to make physical models. During the design process. however, the designer might wish to transfer the design idea into the computer. If he has already made a physical model, it will take him much time to recreate the same model on the screen by means of his CAD programs. This would be different if it were possible to digitize the existing physical model and then to continue designing on the computer. In this paper, the author describes some 3D-scanning methods based, on computer tomograms. Also the inverse combination of modeling and digitizing would be useful. So-called 3D-printing methods could help architects to transform their model on the screen into physical models during or at the end of the computer supported design process.

In this paper, the author will give a survey on how designers can use input and output devices to generate digital data from a physical model and - vice versa - to transform a digital design solution into a physical model. The reader will get an impression of both procedures from the examples given.

summary Creativity is always interested in many fields, in particular, creativity and design creativity have many interpretations (Boden, 1991; Gero and Maher, 1992, 1993; Kim, 1990; Sternberg, 1988; Weisberg, 1986). In early conceptual design process, designers used large number of sketches and drawings (Purcell and Gero, 1998). The sketch can inspire the designer to increase the creativity of the designer’s creations(Schenk, 1991; Goldschmidt, 1994; Suwa and Tversky, 1997). The freehand sketches by conventional media have been believed to play important roles in processes of the creative design thinking(Goldschmidt, 1991; Schon and Wiggins, 1992; Goel, 1995; Suwa et al., 2000; Verstijnen et al., 1998; Elsas van and Vergeest, 1998). Recently, there are many researches on inspiration of the design creativity by digital media(Liu, 2001; Sasada, 1999). The digital media have been used to apply the creative activities and that caused the occurrenssce of unexpected discovery in early design processes(Gero and Maher, 1993; Mitchell, 1993; Schmitt, 1994; Gero, 1996, 2000; Coyne and Subrahmanian, 1993; Boden, 1998; Huang, 2001; Chen, 2001; Manolya et al. 1998; Verstijinen et al., 1998; Lynn, 2001). In addition, there are many applications by combination of conventional and digital media in the sketches conceptual process. However, previous works only discussed that the individual media were related to the design creativity. The cognitive research about the application of conceptual sketches design by integrating both conventional and digital media simultaneously is absent.

title Cost evaluation in design with form features
source Computer-Aided Design, Vol. 28 (12) (1996) pp. 879-885
summary Reducing the cost of a product at the design stage is more effective than at the manufacturing stage. In this paper, an attempt is presented to quantify the manufacturing cost in feature-based design. Machining form features are classified as simple and complex. The machining cost of a part depends not only on the type of form features, but also on the relationship among the features. This cost is calculated for four different cases: traditional machining, simultaneous machining, simultaneous set-up and changeover, and multiple machine tools. A manufacturing process is represented with a digraph. The feature-based evaluation of manufacturing cost is formulated as the shortest path problem, and a mathematical model as well as an algorithm are presented to determine the minimum cost design alternative.

title Phase(x) - memetic engineering for architecture
source Automation in Construction 9 (4) (2000) pp. 387-392
summary Phase(x) was a successful teaching experiment we made in our entry level CAAD course in the Wintersemester 1996/1997. The course was entirely organized by means of a central database that managed all the students' works through different learning phases. This set-up allowed that the results of one phase and one author be taken as the starting point for the work in the next phase by a different author. As students could choose which model they wanted to work with, the whole of Phase(x) could be viewed as an organism where, as in a genetic system, only the "fittest" works survived. While some discussion of the technical set-up is necessary as a background, the main topics addressed in this paper will be the structuring in phases of the course, the experiences we had with collective authorship, and the observations we made about the memes2 that developed and spread in the students' works. Finally we'll draw some conclusions in how far Phase(x) is relevant also in a larger context, which is not limited to teaching CAAD. Since this paper was first published in 1997, we have continued to explore the issues described here in various projects3 together with a growing number of other interested institutions worldwide. While leaving the paper essentially in its original form, we added a section at the end, in which we outline some of these recent developments.

title Localization and comparison of two free-form surfaces
source Computer-Aided Design, Vol. 28 (12) (1996) pp. 1017-1022
summary Comparison of two free-form surfaces based on discrete data points is of paramount importance for reverse engineering. It can be used to assess the accuracy of the reconstructed surfaces and to quantify thedifference between two such surfaces. The entire process involves three main steps: data acquisition, 3D feature localization and quantitative comparison. This paper presents models and algorithms for 3D featurelocalization and quantitative comparison. Complex free-form surfaces are represented by bicubic parametric spline surfaces using discrete points. A simple yet effective pseudoinverse algorithm was developed andimplemented for localization. It consists of two iterative operations, namely, constructing a pseudo transformation matrix and point matching. A computing algorithm was developed to compare two such surfacesusing optimization techniques. Since this approach does not involve solving non-linear equations for the parameters of positions and orientations, it is fast and robust. The algorithm was implemented and testedwith several examples. It is effective and can be used in industry for sculptured surface comparison.

summary The pedagogic approach in the architectural field is suffering a deep change taking in consideration the impact that has been produced mainly by the CAD and multimedia procedures. An additional view to be taken in consideration is the challenge produced by the influence of advanced IT which since 1990-92, has affected positively the exchange of information among people of the academic environment. Several studies confirm this hypothesis, from the wide cultural spectrum when the digitalization process was emerging as an alternative way to data processing (Bateson 1976) to the pedagogical-computational side analyzed by (Papert 1996). One of the main characteristics indicated by S. Papert (op.cit) is the idea of "self teaching" which students are used everywhere due to the constant augment of "friendly" software and the decreasing costs of hardware. Another consequences to point out by S. Paper (op.cit) is that will be more probably that students at home will have more actualized equipment that most of the computer lab. of schools in general. Therefore, the main hypothesis of this paper is, "if we are able to combine usual tutorials design methods with the concept of "self-teaching" regarding the paradigmatic architectural models that are used in practically all the schools of architecture (Le Corbusier, F.L.Wright, M.v. der Rohe, M.Botta, T.Ando, etc.) using a Web site available to everybody, what we are doing is expanding the existing knowledge in the libraries and fulfill the future requirements of the newly generations of students".
